Feasibility & Planning
Investment modelling. Real numbers from real data.
Solar, battery, demand response, tariff alternatives. Modelled against your actual consumption. Updated monthly as conditions change.
What the vendor says
Payback period

What the data shows
Payback period
4.2 years
Based on
12-month 15-min interval data
Site-specific production model
Optimal tariff after solar
In this case, the vendor overestimated payback by 11 months because they used average consumption instead of actual load profile. The real payback is shorter because peak self-consumption is higher than average suggests.
What gets modelled
Five technologies. Every one modelled against real data.
No assumptions. No industry averages. Every feasibility study uses the actual consumption profile, actual tariff structure, and actual site conditions for the specific building.
How it works
Not a one-time report. A living financial model.
Traditional feasibility studies are snapshots. Ours update every month as tariffs change, consumption shifts, and incentive programs open or close. The numbers you see are always current.
Model against actual consumption
12 months of 15-minute interval data. No averages.
Calculate real payback
Site-specific production, self-consumption, actual tariff rates.
Update monthly
Tariff changes, consumption shifts, new incentives reflected automatically.
Alert on threshold
When payback crosses target, you know. Not six months later.
Source competitive quotes
Vendor-ready specs. Three quotes. Apples-to-apples comparison.
Validate vendor proposals
Model vendor claims against real data. Find the gaps before signing.
Tariff simulation
Model 5 tariff alternatives against 12 months of real interval data.
Most businesses are on the wrong tariff. The Broker models every available rate structure against actual consumption shape and identifies the structure that fits the load profile best.
Real-Time Pricing is the best fit for this load profile because 62% of consumption occurs during off-peak hours. Annual savings of $28,800 against the current flat rate. Risk profile: moderate. Sensitivity analysis available.
Vendor validation
A vendor quotes $80K for solar with a 3.5-year payback. Your AI team checks the math.
Vendor proposals are sales documents, not engineering documents. The Consultant models every claim against actual site data and surfaces the gaps before the contract is signed.

Wattif analysis
4.8 years (production) or 3.9 years (with tariff switch)
Real payback 11-38% longer than quoted without tariff optimization
Recommendation: Negotiate based on site-specific production. Switch tariff post-install. Actual payback with both adjustments: 3.9 years. The project is still worth doing. The vendor just needs better numbers.
Ongoing intelligence
Not a one-time study. A living financial model that updates every month.
Most feasibility studies are snapshots that become outdated the moment tariffs change. With Wattif, the numbers stay current. You see updated ROI, tariff recommendations, and performance verification every month. The decision gets clearer over time, not stale.
Ask WattifMonthly ROI updates
Actual generation vs financial model. Performance ratio tracked. Degradation curve compared to spec. You see the value every month.
New opportunity alerts
When battery payback crosses your target, you know. When a DR program opens enrollment, you know. Every new opportunity surfaced automatically.
Post-install verification
Compare actual generation against vendor promises. Surface underperformance early. Hold vendors accountable with real data.
